BROWNVILLE, Neb. (AP) — Nebraska Public Power District says an alert system problem caused several sirens to unnecessarily sound near the district’s nuclear power plant near Brownville in southeast Nebraska.
The sirens went off around 8:15 a.m. Tuesday at Cooper Nuclear Station. The district said in a news release that there was no problem at the plant that required activation of the sirens.
The false alarm is being investigated. District spokesman Mark Becker says the incident is being reported to federal regulators as well.
